Xbox 360 Media Center problem

[liks]

I have tested and connected xbox 360 to laptop with ethernet cable and it worked.

But I have xbox 360 connected to internet. I cannot make it to work sharing through network.
Internet on xbox 360 is working fine.
I have Norton Internet Security 2010 (disabled it but it's not working).
When I go to Media Center in Windows 7 it says 'Extender not found'

I have pc(connected with ethernet cable) and laptop(wireless) and xbox is connected with ethernet cable like this:

(I think my ISP blocked my admin interface)

I can find my xbox in my network map
